173.
Insecure high-school kids latching onto whatever cultural or subcultural stereotype they can in order to 'fit in.' This is a manifestation on an undifferentiated ego-mass striving for conformity and order in a complex and difficult social environment, such as high-school. Most of these kids will outgrow it by their mid 20s. And, will discover that 'being themselves' is the best option of all.
Middle and upper class Black kids trying to be 'gangsta.'
Middle and upper class White kids trying to be 'punk.'

'Derek is such a poser. He talks all 'street' and listens to all the latest gangsta-rap from LA. When in fact, he grew up in Georgetown and his dad is an executive at IBM.'

Any one who does not follow his/her own ideas of what he/she likes. Following no one set norm makes you real and following no one set norm makes you poser. Poser is governed not by the clothes, music, or makeup you wear, but rather by the state of your mind and the conformity to your own beliefs.
Posers conform to the beliefs of others.

a person - usually in middle or high school, who is insecure about him/herself and trys very hard not to be a "conformist" or a "prep," by doing things like: purchasing a skateboard or guitar, purchasing a great deal of clothing and accessories from hot topic, and listening to pop-punk bands such as simple plan, yellowcard, etc. usually, this supposedly "nonconformist" behavior just backfires on him/her, because now he/she is still conforming, just to a different group of people. so the moral of the story is to be yourself.
some people are posers.

A poser is someone who tries hard to be something they arent. Usually, posers call other people posers because they are jealous that the person they called a poser is more skater/stoner/goth/punk/rocker/grunge/etc. than they will ever be.
